Ori firing against a lead plate of 5 millimetres it was enorm, that the cartridge completely deto, 'natedbut had not sufficient power to pierce the lead plete. Thus according to the new method.

this eppees to be the limit charge, while veceording to the known method the limit charge lies above 0.2 gramme erlitt. It is particularly mentioned, 'that all cartridges were closed and Without inner cap stud that the oriergel was pressed et ordinary pressure. ilieexperixrients were carried out marier various conditions elweys yielded. the seme result'.
